If you have (or are looking to buy) the FatShark Dominator goggles then keep reading this page for I will reveal what the best module for the FatShark Dominator goggles is.
During these tests I tried two of the best single receiver modules out there and compared them:
- The Nexave 5G8 By ImmersionRC
- The TBS Dominator RX (5G8) By Team Black Sheep
I also looked at diversity modules and compared the following:
- 2Pineapples Diversity for Fatshark DOM
- LaForge Diversity Module
I didn’t include the Furious FPV FSV2444 Fatshark module since it has been declared as a defect by its manufacturer and is no longer made. Also, I am waiting for the release of the True-D Rx Diversity Furious FPV. When that module comes out I’ll be sure to review it!
So What Is A Diversity Module?
You’ll be pleased to know that a diversity module is actually quite simple. The term “diversity,” describes a module consisting of two independent receivers with their own electronics and own antenna. This means that the best reception is usually based on the signal strength. It is important to note shat some modules have two antennas but only one receiver. If this is the case, it is not a diversity module, even if the marketing tends to use that term. We have seen this in the case of the FatShark module. So is the FatShark module less efficient than a two receptor module? Yes, in theory. But in practice it remains to be seen if this is actually the case. Some diversity modules use antennas that are very close to each other and therefore having two antennas makes very little difference.
Test #1 – 2Pineapples Diversity for Fatshark DOM VS LaForge
In this test we used the FatShark Dominators. We added the 2Pineapples Diversity for Fatshark DOM and the Nexwave 5G8 module by Immersion RC (single reciever.) The antennas used in all of the modules were the Aomway Leaf Clover supplemented by SpiroNet 8dBi Patch by ImmersionRC.
The first thing that I noticed was that the space gain is low between Mono and Diversity modules. However, when the drone passes through obstacles like trees, the space gain increases. However, it does not fully take over the screen.
Its important to note, however, that the manufacturers have used nice clean interfaces. The Nexwave module allows one to select a frequency with 8 external keys. However, to change some options you need to open up the module hatch and edit them – this is something which is not practicle at all.
On the 2Pineapples module, the interface is shown on an OSD display.You can change the options in the menu by quickly pressing the frequency change keys. There is also a frequency scanner that automatically detects the transmission frequency of your multirotor.
The LaForge module has to be my favourite though. Whilst it does not pass as having an OSD, it still offers an OLED display and a jog dial. This means
LaForge The module is even more successful.It does not pass through an OSD, but offers an OLED display and a jog dial. The walk through the menus is very effective. Bonus: the frequency is indicated in large on the screen during a flying session, which allows other drivers to see at a glance the frequency used. The downside: you have to acquire a main module and a second module, and then install them on the glasses, either side of the frame. In contrast, the FlyingLemon module holds entirely in the trap on the dedicated Dominator closed by a piece 3D printed, provided, perforated to allow to remove the heat. The disadvantage: the two antenna connectors are very close, too much for some configurations, especially with a patch antenna (it takes a little force).
